MECHANISM FOR OPERATING- DUMP-GARS.

Specification of Letters Patent. Patented Sept. 12, 1911- Application filed September 14, 1907.. Serial No. 892,878.

To all whom it may concern:

Be it known that I, FRANK S. INcoLDsBY, a citizen of the United States, residing at St. Louis, State of Missouri, have invented ,a certain new and useful Improvement in Mechanism for Operating Dump-Cars, of which the followin is a full, clear, and exact description, re erence being had to the accompanying drawings.

The object of this invention is to provide simple and eflective mechanism for autodump cars when they reach a desired point on the track.

The device is particularly valuable where a car is being used to carry material from a loading point out onto a trestle, thus saving one man at the unloading point.

ropelled by a locomotive or by endless cahle. An instance in the latter case where it is especially useful is where waste product from a mill is being carried to a dump.

' The invention is well adapted for application to cars of the Ingoldsby type, wherein there is a central longitudinal member to which are hinged dumping doors which swing downwardly at their outer edges to discharge the load. With such cars the automatic devices may be arranged to dump the entire car at one place orhalf of it may be dumped at one point and the remainder at anot er.

The invention is hereinafter more fully described and its essential characteristics set out in the claims. 7

The drawings illustrate my invention as applied to an Ingoldsb car. Figure 1 is a side elevation of hal of such car. Fig. .2 is an enlarged cross section of a car, the right hand half of this figure being in a plane indicated by the line AA of Fig. 1, while the left hand half is in a plane nearer the center of the car, as indicated by the line B-B.

Referring to the drawings by reference numerals, 9 represents the side of the car; 10 the inclined end floor; 11 the central longitudinal member, which is shown as ridge shaped; 12 the-load-supporting and dumping doors; 13 the floor beams which carry these doors and which are pivoted to the central member; 15. the .hooks carried by the sides of the car for engaging and supporting the floor beams. This much of the .constructionis usual Ingoldsby' cars,

wherein there is also a pivoted operating lever connected'by links with the hooks .15.

In the present car,'instead of the usual ivot,

this lever 20 is provided with a hook ed catch 22 which normally latch 23 pivoted at 24 to the car side. Pivoted at 25 to the car side, or to means carried engages a gravity thereby, .and below the latch 23 is a freely depending operatinglever. This lever has a long arm 26 and a short arm 27 projecting at an angle thereto and adapted to raise the latch when this lever is operated. The invention is adaptable to either cars Located at a point along the track where it is desired to effect the dumping is a suitable bumper 30 which is shown as a peak or inverted-V secured to the ties. This bumper lies directly in the path of the long arm '26 of the pendulum lever. When the car moving along the track, in the direction of the arrow in Fig. 1, comes to the dumping point, the arm 26 engages the bumper 30 and is swung thereby toward the end of the car. This movement'causes the short arm 27 to engage a lug 28 on the latch 23 raising that latch to release the lever 20.

Coincident with this release or shortly thereafter the lower end of the lever 20 engages the bumper and is swung thereby toward the end of the car, thereby swinging the hooks 15 to release the floor beams and thus dumping the car. This dumping position of the parts is illustrated by dotted lines in Fig. 1. To insure the lever 20 re turning idly over the bumper 30, I provide its upper end with a counterweight 29 which gives it a slight movement in addition to that given by the bumper when it is released, thus causing it to certainly clear the bumper on the. return movement The lever 26 does engage the bumper on the return movement but simply swings idly in reverse direction.

The bumpers 30, as shown, are flat straps bent into an inverted V. form and having laterally projecting ends which are spiked to' the ties 8. The bumpers may be opposite bumpers being properly placed laterally so means independently of the car standing as to be in the path of levers 26 and 20, I arrange the inner edge of the bumper to engage the base of the rail 7.

It will be seen that this mechanism is very simple in construction, and does not interfere with the ordinary dumping, of the car by hand whenever desired. I

The bumpers may be located at any point along the track and may be conveniently moved from place to place as frequently as required.

Having described my invention, I claim:

1. The combination of a dum car having a dumping door and depending operating lever, and means located adjacent to the track for unlocking and moving said lever.

2. The combination of a dump car having outwardly discharging doors, supporting hooks and a depending operating lever, and means located adjacent to the track for unlocking and moving said lever.

3. The combination with a dump car having a dumping door, supporting mechanism, an operating lever for said mechanism, a latch for the operating lever, and mechanism adapted to be engaged by a stationary projection for operating said latch and lever.

at. The combination with a dump car having a dumping door, supporting hooks on the side of the car, an operating lever linked to said hooks", a latch for the operating lever, and mechanism adapted to be engaged by a stationary projection for operating said latch and lever.

5. In a dump car, the combination of a load-supportingdoor, of supporting and releasing mechanlsm, a lever for operating the same, a gravity latch for restraining. said lever, and a depending lever for operating said latch.

6. In a dump car, the combination of a release lever, a latch for restraining it, a lever for releasing the latch, and means carried independently of the car and adapted to be engaged by both levers. I 7.
